While there has been a good amount of debate about ‘the canon’ in philosophy, in many respects substantive discussions about it have only just begun. A large number of relevant questions have been left largely untouched so far, from the identification of the norms that underpin the act of ‘collecting’ figures and texts into a canon to the explanation of the roles canons play in philosophy, and whether these roles change over time or over philosophical sub-fields. The editors’ introduction provides a vue d’ensemble of the book and explains how each chapter contributes to some of these central questions.
